QUESTION copy site on localhost

[krlllo]

Thank you! I managed to change the base url in the settings and now it works more or less (not the pictures, but I can do without). Where/how should I declare a base path and components?

You can change the URLs manually. Migrate plugin does not change every url on the website. I use notepad++ for that.
Make a backup just in case you end up replacing things you don't want. 
Open all the pages on the theme and replace what you want on notepad++. 
For example: you can replace everything that begins with https://www to http://localhost and choose to replace it on every opened document (if you are using notepad++). You can also do that for posts in news manager for example. 
That is also how I update all the old plugins to https when a browser detects that a link is not secure. 

You can replace anything very quickly this way.
